Tekkaman: The Space Knight is an anime produced by Tatsunoko Productions in 1975. A short-lived English adaptation aired in the US in 1984.
Two decades later, it was followed by the much more popular Tekkaman Blade, which was dubbed in the U.S. by Saban as Teknoman. The original series is currently streaming in North America via Yomiura Group's planned Anime Sols video service, as of spring 2013. However, due to the failure to successfully crowd-fund it for DVD, the show will soon be removed from the site, with the possibility of considering a crowd-funding opportunity in the future.
